[R] Ploting a matrix

[skrug]

Sorry for the mistake. As you probably already guesed, I am just 
starting using R. I could not name the difference between a matrix and a 
data.frame.

 > str(b)
'data.frame':   9 obs. of  7 variables:
 $ Datum: Factor w/ 9 levels "06.03.","07.03.",..: 1 2 3 4 5 6 7 8 9
 $ X1   : int  408 335 2123 4685 7669 17060 31330 70730 109667
 $ X2   : int  230 241 1509 2226 7839 13997 24797 53133 93061
 $ X3   : int  25 16 38 61 114 299 140 172 196
 $ X4   : int  248 588 2083 2071 4563 9798 17611 38554 82354
 $ X5   : int  407 201 1339 3699 8375 19200 36563 83993 123167
 $ X6   : int  248 730 3056 2327 4092 8905 15931 37895 84565



Thanks
